Is there a specific app this action is for?
Marketing automation as many users rely on hubspot as a marketing automation platform (MAP). This should be fairly easy to implement given

Specifically a LOT of actions are related to that, there was a previous PR (#17844) but sadly only listing of these elements were added, while you'd ideally want to be able to :

• Duplicate/create a form
• Edit fields on the form
• Clone/create a Page
• Edit Page
• Clone/create a Email
• Clone/create a Workflow

Please provide a link to the relevant API docs for the specific service / operation.
